Studying oyster fossils can help paleontologists discover how long the oyster lived, and in what conditions. If the oyster struggled for survival, the rings would be thinner.
Explain how correlation allows individual rock layers to be traced from one place to another. • Describe how relative dating methods allowed the geologic time.
You might consider a new method to study the age of your dog to be able to tell if your bones contain strata with dates a fossil, i. By looking at a fossil, you may be able to date the object to a fossil during the time when the object was formed. By determining a rock layer, you’re telling us about its age and the features found in the rock that make up that rock. These features are usually incorporated into minerals in your bones, like uranium, potassium, rubidium, rubismite, titanate or zircon crystals.
These tell us a lot more about the objects and processes they affect in Earth’s past than what we might initially have thought.

Relative and Absolute Dating
There are two types of age determinations. Geologists in the late 18th and early 19th century studied rock layers and the fossils in them to determine relative age. William Smith was one of the most important scientists from this time who helped to develop knowledge of the succession of different fossils by studying their distribution through the sequence of sedimentary rocks in southern England.

Geochronology is the science of determining the age of rocks , fossils , and sediments using signatures inherent in the rocks themselves. Absolute geochronology can be accomplished through radioactive isotopes , whereas relative geochronology is provided by tools such as palaeomagnetism and stable isotope ratios. By combining multiple geochronological and biostratigraphic indicators the precision of the recovered age can be improved.
Geochronology is different in application from biostratigraphy, which is the science of assigning sedimentary rocks to a known geological period via describing, cataloging and comparing fossil floral and faunal assemblages. Biostratigraphy does not directly provide an absolute age determination of a rock, but merely places it within an interval of time at which that fossil assemblage is known to have coexisted.
Both disciplines work together hand in hand, however, to the point where they share the same system of naming strata rock layers and the time spans utilized to classify sublayers within a stratum.
